Calculation of the Jahn-Teller parameters with DFT / Izračunavanje Jan-Telerovih parametara primenom teorije funkcionala gustine
(Serbian Chemical Society, 2019)
In this review, we present Density Functional Theory (DFT) procedure to calculate the Jahn-Teller (JT) parameters in a non-empirical way, which does not depend on the system at hand. Moreover, the Intrinsic Distortion Path ...
Kome će stići pismo adresirano imenima elemenata iz Periodnog sistema
(Centar za promociju nauke, 2019)
Да бисмо одговорили на ово необично питање, морамо да се осврнемо на неколико прича о Периодном систему елемената. Како ред налаже, почећемо од његовог открића, преко развоја, а завршићемо приказом његовог данашњег облика.
Estimation of lipophilicity of n-substituted 2-alkylidene-4-oxothiazolidines by means of reversed-phase thin-layer chromatography
(Taylor & Francis Inc, Philadelphia, 2011)
The chromatographic behavior of 23 new 2-alkylidene-4-oxothiazolidine derivatives was investigated by means of the reversed-phase thin-layer chromatography (RP TLC) on the C18 and CN stationary phases. Binary mixtures of ...
Kinetics of sintering of polyethilene glycol and lanthanum doped aluminum oxide obtained by the sol-gel method / Uticaj dodatka polietilen-glikola i lantana na mehanizam sinterovanja aluminijum-oksida dobijenog sol-gel postupkom
(Association of Chemical Engineers of Serbia, 2011)
Sintering and crystallization of low-density polyethylene glycol (PEG) and lanthanum, La(III)-doped Al2O3 aerogels prepared from aluminum isopropoxide were investigated. The sintering behavior of non-doped and doped aerogels ...
Effect of supplemental feeds on liver and intestine of common carp (Cyprinus carpio) in semi-intensive rearing system: Histological implications
(Springer Nature, 2016)
In order to determine effects of different types of supplementary feed on the histology of liver and intestine of carp reared in a semi-intensive system, a six-month field experiment was carried out. Carp yearlings were ...
Forced periodic reactor operation with simultaneous modulation of two inputs: Experimental investigation based on Nonlinear Frequency Response Analysis
(The 25th International Symposium of Chemical Reaction Engineering (ISCRE 25), Florance, Italy, 2018)
Theoretical evaluation of possible reactor improvement for periodic operation. Automated experimental setup was built, with a lab-scale CSTR and adjustable flow-rates, in which periodic operations can be conducted. The ...
Spectroscopic properties and antimicrobial activity of dioxomolybdenum(VI) complexes with heterocyclic S,S'-ligands / Spektroskopska svojstva i antimikrobna aktivnost dioksomolibden(VI) kompleksa sa heterocikličnim S,S'-ligandima
(Srpsko hemijsko društvo, Beograd, 2012)
Five new dioxomolybdenum(VI) complexes of the general formula [MoO2(Rdtc)2], 1-5, where Rdtc- refer to piperidine (Pipdtc), 4-morpholine (Morphdtc), 4-thiomorpholine (Timdtc), piperazine (Pzdtc) or N-methylpiperazine ...
Core-shell structured tungsten-tungsten carbide as a Pt catalyst support and its activity for methanol electrooxidation
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Tungsten carbide was synthesized by calcination of carbon cryogel containing tungsten in a form of metatungstate. Characterization by X-ray diffraction and transmission electron microscopy indicated core-shell structure ...
Semiquinol and phenol compounds from seven Senecio species
